How to properly setup Windows7 to use Selenium with Firefox [TDD with Python]?

Question

I\'m getting my system (Windows 7 Pro 64 bit, Python 3.5 through Anaconda) setup to use Firefox through selenium to follow the book Test Driven Development with Python.<

1. Selenium used to reference a driver called wires.exe (github-geckodriver issue 90). As of Selenium3 that driver has been replaced with geckodriver.exe. Install/upgrade to the latest selenium by running pip install "selenium>=3.0.0"
2. Download the latest geckodriver for your platform: as of this writing that would be geckodriver-v0.11.1-win64.zip for 64 bit or geckodriver-v0.11.1-win32.zip for 32 bit. In your case the version %1 error has to do with an incorrect geckodriver version. Extract this zip to C:\Users\YourUserName\Downloads\selenium_driver
3. Install the Firefox Extended Support Release setting the custom installation path to C:\Program Files\Mozilla FirefoxESR if on 64 bit or C:\Program Files (x86)\Mozilla FirefoxESR if on 32 bit.

If setting the Windows PATH to C:\Users\YourUserName\Downloads\selenium_driver doesn't seem to work (so that selenium can find geckdriver.exe) you can instead specify its directory in your Python script as follows:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
gecko = r'C:\Users\YourUserName\Downloads\selenium_driver\geckodriver.exe'
ffox_binary = FirefoxBinary(r'C:\Program Files\Mozilla FirefoxESR\firefox.exe') #for 64 bit installation
#ffox_binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla FirefoxESR\firefox.exe') #for 32 bit installation
browser = webdriver.Firefox(firefox_binary=ffox_binary, executable_path=gecko)  
browser.get('http://localhost:8000')
